Analog disinfection sensor

Trace sensor for drinking and industrial water treatment

  • ©Endress+Hauser

CCS141 is the analog sensor for trace measurement of free chlorine. It delivers reliable values even if fluctuations in flow or conductivity occur and allows control of the disinfection loop so that the water is free of germs. At the same time, the sensor is designed for long calibration and service intervals reducing your maintenance effort.


  • Recalibration intervals approx. 1 to 4 months under constant operating conditions

  • Easy membrane replacement thanks to prefabricated membrane cap

  • Measured values are not affected by conductivity fluctuation

  • Measurement virtually independent of flow rate in the range above 30 l/h

  • Zero-point calibration not required. No complex installation of an activated carbon filter, as found with open chlorine sensors.

Field of application

CCS141 measures free chlorine in:

  • Drinking water
    - Trace measurement in process water and distribution networks
    - Monitoring, control and optimization of disinfection processes
